Nikolay Davydenko will play in the Rogers Cup tournament this week amid an investigation into irregular betting patterns on one of his matches. The Association of Tennis Professionals said it had no plans to suspend him or ask him to sit out.
"It is important that we not jump to conclusions, especially when players' reputations could be unfairly tainted," ATP executive chairman Etienne de Villiers said. "What we must do is carry out a comprehensive and immediate investigation, and that is what we are doing."
Davydenko is seeded fourth and won't play until the second round Wednesday.
Also, qualifier Robin Haase upset 10th-seeded Tomas Berdych 6-4, 7-5 in the rain-delayed first round of the tournament. Lleyton Hewitt beat Juan Carlos Ferrero 7-6 (7-5), 6-4 in a matchup of former top-ranked players.
